Naxos (Greek:Ναξος is a Greek island, the largest island (428 kmē) in the Cyclades island group in the Aegean. It was the center of archaic Cycladic culture.

The largest city and capital of the island is Hora, sometimes called Naxos City, with about 12,000 inhabitants. The main villages are Filoti, Apiranthos, Tragea (Chalki), Koronos, Sangri, and Apollonas.

Naxos is a popular tourist destination, with several easily accessible ruins. It has many beautiful beaches, such as those at Agia Anna, Agios Prokopios, Alikos, Kastraki, Mikri Vigla, Plaka, and Agios Georgios, most of them near Hora.

Naxos is the most fertile island of the Cyclades. It has a good supply of water in a region where water is usually inadequate. Mount Zas (1,008 meters) is the highest peak in the Cyclades, and tends to trap the clouds, permitting greater rainfall.
